HYDROCARBON-MOTOR.

Application filed July 10, 1913. Serial N 0. 778,316.

To'all whom it may concern Be it known that I, RUssELL HUFF, a citizenof the United States, and resident of Detroit, Wayne county, State of Michigan, have invented certain new and useful Improvements in Hydrocarbon-Motors, of which the ,auxiliary the splash the cranks and connecting rods into the oil contained in the bottom of the crank-case or by the oil thrown from the connecting rod bearings and main crank-shaft bearings caused by the excess of oil supplied to these hearings under considerable pressure. In

" some cases, and particularly when the motor is idling, this causes an excess of oil to be thrown upon the cylinder walls and 1f the pistons are not quite as tight as they should be, more or less of the oil will be drawn into the combustion chamber of the piston by reason of the suction therein and it will be burned and expelled from the exhaust in the formof smoke. This is of course wasteful of oil and the smoking is objectionable and the interior of the motor receives an unnecessary deposit of carbon.

One of the objects of the present invention is to provide a baflle at the lower open end of the cylinder to prevent this excess of oil from reaching the cylinder walls. This battle is preferably of such form that it extends somewhat below thelower end of the cylinder and surrounds the skirts of the piston when the latter is at the bottom of its stroke. The lower ends of, the downwardly extending part of the bafile are formed wlth approximately horizontal flanges which prevent oil being splashed directly into the cylinder. I

. Another object of the invention is to provide a downwardly extending bafile in the crank-case onthat side of the case in which the crank is moving on its up stroke, and as 'the cam-shaft is located in this side of the Specification of Letters Patent.

' crank-case also,

filnmost f the hydrocarbon motors used,

, which forms the \base of oil; caused by the dipping-oi Patented May 2,191 e.

a further object is to form this bafile-so. that the oil will be splashed fromit to the cam-shaft and its bearings,

Other objects from the following description taken in connectlon with the drawings, in which Figure 1 1s a transverse sectional view .through a motor embodying this invention; and F igs. 2, 3, and 4 are enlarged top, side,

and vertical sectional views respectively of the baffle.

Referring. to the drawings, 10 represents jthefmotor crank-case formed in the present instance, in two parts, the upper part 11 of of the motor, and the lower part 12 of which forms the sump or oil well of the motor. In this crank-case are the main bearings 13 which support the crank-shaft 14, from the crank pin 15 of which extends the connecting rod 16 which is operated by the piston 17 working in the cylinder 18 which is mounted upon and secured to the upper part 11 of the crankcase.

The cylinder shown is of the L type having puppet valves 19 at one side which valves are operated by push rods 20 from a camshaft 21 which is mounted in suitable bearings on the interior of the crank-case 10. The crankshaft adapted to operate in a clockwise direc tion, as shown by the arrow 22, so that the crank pin 15 is on the downward stroke in Fig. 1. With the crank moved 180 degrees from the position shown it will be on its up stroke, at which time it will have a tendency to splash oil from thebottom of the crank-case up into the cylinder. Also if oil is fed under pressure from the crank-shaft drawings.

For the oil from and cylinder wallsQa bafiie 22 is arranged between the. cvlinder and crank-case. As

purpose of preventing too much shown, this ba'flie comprises a ring portion of the invention will be seen.

of the motor shown isbeing splashed on to the piston above the crank pin in the position inv which it is shown in the 23-split at 24; southat it may be sprung into place in the opening which is concentrically arranged directly below the open end of the cylinder. This split ring has an annular fiangeQG which is clamped between the cylinder .and the crank-case, aS shown in Fig, 1, and apin 27 and a notch 28 in the flange 26 position the bafi'le properly so that it will not interfere with the connecting rod.

The ring portion of the baiile is extended downwardly into the crank-case on that side only of the case in which the crank is moving when on its up stroke, that is on the side of the crank-case opposite to that in which the crank pin 15 is located in Fig. 1. This downwardly extending portion or skirt 29 thus protects from oil splash the lower part of the piston when it is at the bottom of its down stroke and it also causes the oil splashed against it to be carried over onto the cam-shaft and its bearings so that they are sure of efficient lubrication.

T he lower edges of the skirt 2%) are provided with substantially horizontal flanges 30, as shown best in Fig. 2, these flanges leaving a transverse slot 31 between them for the passage of the connecting rod 16. In the form of the baffle shown, the part ofthe ,skirt 29 which is at one end of the slot 31 is bent outward slightly, as at 32, for the purpose of giving the connecting rod plenty ofclearance. The inner edges of the flanges 30 may also be provided with down turned lips 33 and the flanges are also inclined slightly toward their free edges, so that any oil which runs down from the cylinder walls may quickly drain from the interior of the baffle into the crank-case.

The cut-away portion 3i of the bafiie may be made larger or smaller as is desired to suit different conditions, the exact amount which the bafiie is cut away at this point being determined by experiment.

The baffle shown is preferably stamped from sheet metal but it will of course be understoodthat it may be in the form of a casting or it may be otherwise built up.

It will also be understood that various modifications may be made from the details of the invention shown without departing from the spirit or scope of the claims.
